I think that there is an error in the reporting, or my ads are really screwed up. When I run the separate reports, I see that my Ad Unit page impressions are generally less than 10% of the page impressions for the Link Units. For example, using fake numbers, if my Link Unit impressions for a day show 5,000 page impressions then my Ad Unit page impressions will be less than 500. In the combined report, the total impressions would show as about 5,500. The page impressions on the combined report never add up exactly, but they are close.

I don't understand how this can be. Every page (except blog, which has no link units) has an Ad Unit and a Link Unit, so the page impressions should be roughly equal. What this report tells me is that the Ad Units are displaying only about 10% of the time that somebody view my pages? Every time I check, both the Ad Unit and Link Unit are there. It seems to me that page impressions for both types should be roughly the same.

Also, the CTR of the Link Units are pathetic, as I always suspected. On the other hand, the CTR of the Ad Units are incredible. The same thing applies to the eCPM's.

So, am I reading this wrong or is it really possible that Ad Units are only rarely displayed on my pages? Again, every time I look the Ad Units are there. BTW, about 75% of my traffic is from the US and the site is US based and hosted.

Link units have two impressions. First when they are seen and second when they are clicked. That also makes the CTR half of an ad unit. And if even after the ads are displayed someone refuses to click and goes to another website the CTR is even lower.
